Mako Matters (Patreon)

(contains human female to feral behemoth TF, mild masturbation)

Spending four years and tens of thousands of gil on going to college turned out to be a huge waste of time. Yeah, a shocking revelation for many with the know-how. Naive people like Vicki had the misfortune of realizing such life truths after the fact.

As the young brunette strained her slender arms to open the valve, she found herself once again thanking mom and dad with a ramble of vulgar curses. She had dreamed of painting landscapes with the region's majestic wildlife, they wanted her to pursue engineering. The selling point of financial stability had a way of winning most of these arguments. And now Vicki got to enjoy that amazing wealth playing mechanic to a mako reactor older than her grandpa, providing power to equally dysfunctional villages in the middle of nowhere.

No sooner had Vicki finished her third fit of the day then the radio on her tool belt crackled to life.

"Yo, handyman? You got the damn ventilation fixed yet?" It was the voice of the onsite manager, Henry, or something, checking in from his office. No surprise there, the man's portly frame was a testament to how often he went anywhere else while on duty. "It's a damn sauna up here. I'm about to start melting."

"Don't do me any favors." Amazingly, that was just the extra surge of anger Vicki needed. The valve finally squeaked on its hinges, setting loose a sharp hiss from inside the pipes. A deep breath helped let Vicki's body relax while turning it completely open so steam could rush to other parts of the plant. Her average female body was not built for this hard labor, even with company materia bolstering it.

"Yeah, the damn coolants are unclogged finally," she said into her radio. "Honestly, the ability of small animals to even get in those ducts is uncanny."

"Good. Speaking of which, I need you to head over to tank one. It's been rattling a bit, and the gauges are saying it might need a patch up."

The corner of Vicki's eye twitched as it checked her cell phone clock. "Sir, my shift ended ten minutes ago, and Ted should already be here for the night watch. If it's all the same, I'd rather…"

"Splendid! That's my girl!" The evil radio box cut Vicki off before her thought could finish. "Ted called in sick, so it'll be an hour or two before a fill-in engineer can drive up here. Gotta love harvesting mako out in the boonies, eh? I'll be heading out for the night, so make sure you got things locked up for when they get here. Okay? See you tomorrow."

Senseless jabbering escaped Vicki's mouth too uncivil worth repeating. Even so, she did not have the nerve to transmit it over the radio. After a few minutes of fuming, she returned the device to her belt. It was a quarter-mile trek to the building housing tank one, and the last sliver of sunlight between hilltops provided little aid in navigating. Besides her, there was only one supervising technician and a few guards setting in for a graveyard shift. Apparently, not enough to warrant sufficient walkway lights.

It was clear there was a problem soon as the chamber door was opened. Vicki's head pivoted from side to side, trying to locate the direction of what sounded like a pot boiling over, smacking her face with whips of clumpy hair in the process. Another reminder she should have been home in a hot bath, maybe planning to sketch up something.

The room's layout was pretty much the same as the other four tanks; a large vat the size and shape of a giant cement mixer sat at the center with several metallic pumps twisting their way deep underground. These were for extracting the bright green fluid resting behind the viewing windows. A system of water and steam cooling kept the highly potent mixture stable until it was ready to be delivered to the reactor for energy conducting.

Vicki did not know the specifics about the strange stuff called mako, just that it powered everything in a civilized society. Some of the workers said it was pure magic straight from the planet's blood, which made no damn sense to her. It seemed no different than pumping oil. Well, except with mako, you can condense it into those cool jewels called materia that give people superpowers. The two inside her company-issued breast pocket pin were a rather weak strength and disease resistance enhancer.

Frankly, a radiation suit would have been more preferable once she found the source of the bubbling noises. One of the siphoner hoses had a bolt fastener rusting off. There must have been a small crack forming to be blowing bubbles with the small trickle of mako leaking out.

Great, if they just left this thing going all day, the plate might be damaged. That meant spending the better part of tomorrow morning replacing the whole damn thing, assuming parts could be ordered. The practice of not maintaining something until it breaks should not be used on a volatile form of energy production, but such was the world Vicki lived in.

For now, the small bottle of rubber sealant from her tool belt would work. A few quick sprays and Vicki was ready to end this lousy day.

CRNCH!

Or the bolt could already be so degraded that a minor spurt of rubber particles was enough to snap it. The thick cap whizzed past Vicki's face missing her eye by inches. Not that she had time to process that near-death miss with a spray of raw mako that began gushing out a wider crack. Her free hand shot up too late to protect her face from being painted with the hot green fluid.

Ugh! A lot of it got in her mouth too. It tasted like drinking copper.

Vicki spat out what she could, trying to refocus on her task through one squinted eye. Fighting with the pressurized leak, she worked around the edges until there was enough sealant to stem the flow. A patch and some tape for good measure left her, mostly, satisfied the hose would not rupture before proper repairs could be done tomorrow. The last thing she needed was for the only decent job option for miles to explode in glowing planet goo.

Speaking of which, the way Vicki's jumpsuit and hair glowed from being soaked in mako was mildly disturbing. Not having decontaminating wash areas installed at any of the pumping tanks was going to be a big talking point come next safety inspection. That meant another long walk to the sleep-in building. Along with beds, graveyard employees also got to enjoy a co-ed shower and bathrooms for basic needs.

Hopefully, cheap discount soap was all Vicki needed for mako exposure. She stripped out of her jumpsuit and underwear too angry over her lot in life to be concerned over privacy. Leaving this gunk on her all the way home was probably not a good idea, and there did not seem to be anyone catching a nap in the beds anyway. That probably meant the replacement engineer was still not back, damn it.

This place really was a pit. Even the shower nozzles squeaked like they would break off in Vicki's hand. There came a hiss from somewhere deep within the pipes, and she was left watching the shower head vibrate long enough to wonder if something else had been clogged. 

Eventually, there came a hiss followed by a strong downpour of water streams. It splashed into Vicki's chest with the expected sharp bite of cold before adjusting to a soothing warmth. Good to know the heaters have not exploded yet.

Vicki rolled her head back with a pleased moan, stepping forward to get her face under the cleansing waterfall. Not just the mako, but ten hours' of sweat and dirt flowed off her smooth skin easing the fatigue off her mind. Hands gently passed across her breasts over her facial features, helping remove the more stubborn grime.

Once she was satisfied with having a relatively clean front, she turned to give her hair and back proper spraying. Hot water cascaded across her butt, causing Vicki to squirm until her skin could adjust to it.

"Mmmh!" Vicki's moaned as she began enjoying the assault of water drops on her shoulders. Hands absently continued to roam between her face and breasts in their light massage. They still felt heated despite not being directly under the shower. Fingers accidentally brushed past an erect nipple, eliciting a louder groan through clenched teeth.

Technically it was against company policy to 'let off steam' while on the property, but this was the same company that valued ten gil in pump repairs over the health of employees. Long as people were not trying to murder the site manager, he was fine with however workers dealt with their stress.

Besides, had anyone been around to watch Vicki feeling herself up, they might have been concerned with how sharp her teeth were getting.

The woman alternated between hugging her shoulders and kneading her soft mounds, getting lost in their tenderness. All the areas mako had soaked through her clothes felt insanely sensitive, giving her little concern about the exposure. Otherwise, she might have noticed when the black nubs sprouted behind her widening ears. It was more pressing to turn slowly, trying to get her body soaked under the downpour of water, hands settling upon her mounds to knead them.

Actually, getting wet became an increasing challenge, with Vicki's body steadily stretching towards the ceiling. Before long, her chest loomed over the showerheads, barely getting a drizzle across her firming stomach. Muscle definition rose out of the gentle surface of her skin into hardening ridges. Something her fingers found amazing to feel while they traced over every limb.

The lack of a proper shower never became an issue with a different kind of wetness distracting Vicki. One hand tentatively roamed over the individual bumps of her swelling abs on its way between her thighs. Her other continued squeezing one boob after the other trying to work through the rising tension in her ribcage.

"Hnngh! Grah!" Vicki gasped upon making contact with her groin. Fingers pressed into the delicate numb inside, sending sparks of newfound pleasure surging into her brain.

Almost in response to this energy, Vicki's face erupted in a slew of mutations. Black nubs sprung out the sides of her head, developing sharp points as they wound a foot in front of her as full horns. The ears under them pulled out into wide points flicking with developing muscles that allowed them to catch sounds better. Large bushes of hair sprouted down the length of her back, following her spines trail to form an animal mane. Nostrils flared bigger and wider with deepening breaths, the woman too lost in her personal pleasuring to hear the popping of her petit nose pushing into her upper lips.

"Paah! Haa haa! grrr…GRWAARR!" One particular spike of pleasure shocked Vicki's system, turning her delighted moans into a bestial roar. Her enlarged ears could not ignore the wild cry resonating off the tiled walls, even with the stimulations bringing her close. "Wha-aah the f-f-fuck!?"

Vicki brought both hands to her mouth just in time to feel it extending out into her palms. Eyes clenched shut tearing at the overwhelming pressure pushing her face out from the inside. Dozens of pricks collided with her fingers running across her stretching face, which Vicki realized was hairs growing in. It was like she gained a five o'clock shadow, only they continued to spread until her face and neck became engulfed in a fine pelt.

It took long after the pain stopped for Vicki to work up enough nerve to open her eyes. The sensation of her ears twitching to catch the sound of her running shower was highly disturbing, much like the nasally way her breathing had changed.

She was still pretty horrified to see a wide animal snout blocking the bottom of her peripheral. Its thick bridge was coated in purple fur leading out to a huge black nose at the tip. Vicki went cross-eyed, watching the rough, wet surface wrinkle with each blast of air out its nostrils.

Footsteps splashed along the wet floor in a beeline for the closest mirrored sink. Vicki stared into the wooden glass frame seeing only her breasts and a hardened six-pack of abs reflected back. Her entire body had grown not just bigger, but incredibly muscular, well beyond the limits of the most hardened soldiers.

"ACK!" Vicki tried to squat down to get her face into the mirror's borders only to pierce if's reflective surface with her horns, making the changing woman aware of their existence. Through the many cracked fragments, she could still make out having the head of a monstrous dog-like creature. Only her curled bangs remained the same with the rest of her hair fluffed into a scruffy mane. The only subtle hint to her former identity. "...why the fuck do I have a behemoths head!?"

The bull horns and razor teeth were iconic to this species of monster. Vicki could easily recognize it despite never having seen one alive. At least she could still talk, although stronger throat and tongue muscles made each word come out like a growl.

"Hnnngh!" A rush of tension sent Vicki recoiling from the mirror. With a loud crack, her collarbone broadened over a foot in both directions. Shoulders inflated with a dense series of large muscles forming a boulder-like roundness. The excess power rolled down her back in a series of bubbling ridges. Fur quickly followed, cascading down her neck to coat her torso and swellings biceps in purple. "Oh, come on! No!"

A deep rumble came from within Vicki's muscular stomach moments before her chest puffed up with a chorus of cracks. Every rib reversed direction to make room for expanding organs, leaving her struggling to stand with such a top-heavy physique. Panicked hands grabbed for her breasts only to have the perky mounds slip away, melting like butter into the flat, firm plates of monstrous pectorals.

The loss of a primary female characteristic finally made Vicki realize these unorthodox mutants were not going to stop. She needed to call for decontamination, or something, anything before security came along and found a behemoth mysteriously stuck in their bunks. This shift had been awful enough without ending on a fight to the death.

Vicki hobbled over to her discarded jumpsuit, forced to hunch from the weight of her changing upper body. Fur had finished covering most her body, wrapping around her pelvis before trickling its way over the dense meat of her thighs. She tried her best to ignore the imposing transformation while fishing out her cell phone from a back pocket. Fingers were becoming increasingly stiff, making it take a few tries to bring up the speed dial for emergency services.

KRRCKLE!

An effort turned moot thanks to enormous black claws spontaneously sprouting from Vicki's fingertips. The unprepared tap shattered the screen in a deep finger divot rendering the flat hunk of metal instantly useless. It promptly slipped from her grasp due to the rest of her hand's shifting. The flesh under the purple fur spasmed as her palms nearly tripled in thickness. She could only stare powerless, watching thumbs reduce to little nubs at her wrists. The rest of her fingers bloated into round digits lacking the joints for gripping objects.

"Mrwar!?" What little gravity Vicki had left gave out, forcing her to land upon her new front paws. She tried to stand, waving the animal extremities awkwardly in the air for a few seconds before being forced to fall back on them. The second attempt would not let her get upright at all.

A glance back revealed the culprit to be her heels tightening into a high arch off the ground. Toes became pressed into the ground as they popped large and round into matching hind paws. Vicki's thick legs themselves shortened somewhat while widening with a grinding spread of her hips. Once finely rounded buttocks flattened into the angular flank of an animal, locking her permanently into a quadrupedal stance.

"Grar! Fucking fantastic!" Vicki snorted through the discomfort of her waning transformation. Paws thumped with the power of her muscular frame as she moved in a circle around the, suddenly small spaced, bunk. This was both to get a look at her alien monster body and figure out how to move on its four beefy legs.

Ironically, she was also trying not to think too hard on both points, less she go into a panic attack that leads into a kaiju-style rampage.

"Is mako supposed to even do this? God damn, that's at least thirty health and safety hazards being neglected. Now, what am...am I supposed...ah...ah ah aaaaaah! What the fuuuuuckaaah!"

Turned out the potent earth energy mutating her form had one last surprise for Vicki. It took the form of a strange tingle at the base of her neck, rolling her spine like she was being petted. Except it hit her rear for a hard crash. Her snarling snout sunk between her forepaws as another force repeated the process, propelling her ass high into the air. A small tent of furry flesh poked out along the top as her tailbone uncurled. With a third, stronger pass, the little bulge exploded out behind Vicki, building upon new vertebrae and quickly wrapping in rich flesh to match her strong form.

The pained roar that escaped Vicki's muzzle actually shattered a few bathroom mirrors before fading into a whimper. As her senses returned, so did the awareness of freshly developed nerves on an appendage human's definitely never had. She remained almost rooted in place, trying to gain some control of the thick mass extending out her backside.

When she looked back, it was with a dejected sigh of acceptance to see a long log of a tail wagging lazily in the air. Its tuft of spiky brown hair matched her mane perfectly.

"Well, ain't that just fantastic!" Grumbling to herself was about the only coping mechanism the fresh behemoth had left to keep her thoughts straight. Here she was tired, angry, and no longer biologically human. Yet, none of that mattered since the company would not pay a lick of overtime for this bullshit.

Honestly, if Vicki was not friends with at least a third of the work staff and townspeople getting this power, she would hurl a tank full of mako right onto the company CEO's front lawn. Being transformed into a monster might end up being a boon for that scum, knowing her luck.

A gentle knocking on the entrance door snapped Vicki out of her thoughts of petty revenge. She spun her hulking body around, accidentally overturning a bed with her tail in the process. Luckily it was not the guards but some unknown blond guy in a jumpsuit entering.

"Uh, hello? I'm Janus, here to replace Ted." The man strolled in, letting the door slam locked behind him. "Is anyone...oh?"

The only thing more amazing than coming face to snout with a snarling monster the size of his truck was how long it took Janus to notice Vicki looming over him. Her snout wrinkled in a snort strong enough to send then man's hair fluttering.

"It's about damn time you got here! I'm two hours into unpaid overtime, and there's a leak in tank one I hope treats you better than it did me." A giant front paw raised up, blocking light over Janus in a way that made him cringe for an expecting strike. Instead, the behemoth moved over him with a trailing view of the many hard ridges of her muscular underside. Vicki would rather head towards the doorway with furious purpose than hurt the fill in. "I'm taking some sick days to get my mako poisoning sorted out. Tell that fat bastard if he tries to call me I'll drop a meteor on his car. And sorry about the door."

"...the what?"

BWOOOSH!

Vicki did not even slow her four-legged stride. With one hard lung, her horns broke through the doorways safety locks, with mountainous shoulders taking out the walls around it. Wood debris was crushed into further dust under her rough paw pads as all the changed monster could think of now was curling up for a good sleep.

Unlike Janus, who could not think at all. The idea a talking female behemoth just screamed at him was still sinking in while he watched it stomp off into the night. Panicked shouts of approaching guards brought his mind back to the present, only to groan at the realization he now had a door to fix. Not to mention the behemoth had muttered something about tank one having issues with her.

"This job is totally worth the two years at art school," Janus mumbled as he started to measure out the Vicki-sized hole.
